MySQL 绿色版安装方法教程

MySQL 绿色版安装方法教程,需要的朋友可以参考下。
一、下载,这里使用绿色解压缩版

http://mirror.services.wisc.edu/mysql/Downloads/MySQL-5.1/mysql-noinstall-5.1.32-win32.zip

二、配置MySQL的参数

1、解压缩绿色版软件到D:\AppServ\MySQL
设置系统环境变量, 在Path中添加 D:\AppServ\MySQL\bin;?

?


2、修改D:\AppServ\MySQL\my-small.ini文件内容,添加红色内容

[client]
#password = your_password
port = 3306
socket = /tmp/mysql.sock
default-character-set=gbk

[mysqld]
port = 3306
socket = /tmp/mysql.sock
default-character-set=gbk
skip-locking
key_buffer = 16K
max_allowed_packet = 1M
table_cache = 4
sort_buffer_size = 64K
read_buffer_size = 256K
read_rnd_buffer_size = 256K
net_buffer_length = 2K
thread_stack = 64K
basedir=D:\Appserv\MySQL\
datadir=D:\Appserv\MySQL\Data\
#basedir是mysql安装目录;#datadir是mysql数据库存放位置,必须是Data文件夹名

将修改后的文件另存为my.ini

3、安装MySQL的服务,服务名自己定义为MySQL.
1)、进入DOS窗口
2)、执行安装MySQL服务名的命令:
D:\AppServ\MySQL\bin\mysqld-nt -install mysql --defaults-file="D:\Appserv\MySQL\my.ini"
出现Service successfully installed.表示安装成功。

然后打开服务窗口(在运行框中输入services.msc即可打开服务窗口,然后可以找到mysql服务了,右键mysql服务属性,在弹出的窗口中可以看到以下信息:)
D:\AppServ\MySQL\bin\mysqld-nt --defaults-file=D:\Appserv\MySQL\my.ini mysql? 则表示mysql会随开机启动而启动!


3)、启动MySQL服务
net start mysql
MySQL服务正在启动 .
MySQL服务无法启动。

4)、登陆MySQL服务器
mysql -uroot -p
Enter password:
Welcome to the MySQL monitor. Commands end with ; or \g.
Your MySQL connection id is 1
Server version: 5.1.32-community MySQL Community Edition (GPL)

Type 'help;' or '\h' for help. Type '\c' to clear the buffer.

mysql>

注意:MySQL的管理员用户名为root,密码默认为空。

5)、查看数据库
mysql> show databases;
+--------------------+
| Database |
+--------------------+
| information_schema |
| mysql |
| test |
+--------------------+
3 rows in set (0.02 sec)

可以看到MySQL服务器中有三个数据库。

6)、使用数据库
mysql> use test
Database changed

7)、查看数据库中的表
mysql> show tables;
Empty set (0.00 sec)

8)、创建表ttt
mysql> create table ttt(a int,b varchar(20));
Query OK, 0 rows affected (0.00 sec)

9)、插入三条数据
mysql> insert into ttt values(1,'aaa');
Query OK, 1 row affected (0.02 sec)

mysql> insert into ttt values(2,'bbb');
Query OK, 1 row affected (0.00 sec)

mysql> insert into ttt values(3,'ccc');
Query OK, 1 row affected (0.00 sec)

10)、查询数据
mysql> select * from ttt;
+------+------+
| a | b |
+------+------+
| 1 | aaa |
| 2 | bbb |
| 3 | ccc |
+------+------+
3 rows in set (0.00 sec)

11)、删除数据
mysql> delete from ttt where a=3;
Query OK, 1 row affected (0.01 sec)

删除后查询操作结果:
mysql> select * from ttt;
+------+------+
| a | b |
+------+------+
| 1 | aaa |
| 2 | bbb |
+------+------+
2 rows in set (0.00 sec)

12)、更新数据
mysql> update ttt set b = 'xxx' where a =2;
Query OK, 1 row affected (0.00 sec)
Rows matched: 1 Changed: 1 Warnings: 0

查看更新结果:
mysql> select * from ttt;
+------+------+
| a | b |
+------+------+
| 1 | aaa |
| 2 | xxx |
+------+------+
2 rows in set (0.00 sec)

13)、删除表
mysql> drop table ttt;
Query OK, 0 rows affected (0.00 sec)

查看数据库中剩余的表:
mysql> show tables;
Empty set (0.00 sec)

三、更改MySQL数据库root用户的密码

1、使用mysql数据库
mysql> use mysql
Database changed

2、查看mysql数据库中所有的表
mysql>show tables;
+---------------------------+
| Tables_in_mysql |
+---------------------------+
| columns_priv |
| db |
| func |
| help_category |
| help_keyword |
| help_relation |
| help_topic |
| host |
| proc |
| procs_priv |
| tables_priv |
| time_zone |
| time_zone_leap_second |
| time_zone_name |
| time_zone_transition |
| time_zone_transition_type |
| user |
+---------------------------+
17 rows in set (0.00 sec)

3、删除mysql数据库中用户表的所有数据
mysql> delete from user;
Query OK, 3 rows affected (0.00 sec)

4、创建一个root用户,密码为"xiaohui"。
mysql>grant all on *.* to root@'%' identified by 'xiaohui' with grant option;
Query OK, 0 rows affected (0.02 sec)

5、查看user表中的用户
mysql> select User from user;
+------+
| User |
+------+
| root |
+------+
1 row in set (0.00 sec)

6、重启MySQL:更改了MySQL用户后,需要重启MySQL服务器才可以生效。
net stop mysql
MySQL 服务正在停止..
MySQL 服务已成功停止。

net start mysql
MySQL 服务正在启动 .
MySQL 服务已经启动成功。

7、重新登陆MySQL服务器
mysql -uroot -pxiaohui
Welcome to the MySQL monitor. Commands end with ; or \g.
Your MySQL connection id is 1
Server version: 5.1.32-community MySQL Community Edition (GPL)
Type 'help;' or '\h' for help. Type '\c' to clear the buffer.
mysql>

如果修改密码后net startmysql出现不能启动mysql的1067错误,则可以使用以下办法解决:
使用cmd命令:D:\Appserv\mysql\bin\mysqladmin -uroot -p shutdown,然后输入密码,再net start mysql 就没有这个错误提示了!

四、数据库的创建与删除

1、创建数据库testdb
mysql> create database testdb;
Query OK, 1 row affected (0.02 sec)

2、使用数据库testdb
mysql> use testdb;
Database changed

3、删除数据库testdb
mysql> drop database testdb;
Query OK, 0 rows affected (0.00 sec)

4、退出登陆
mysql>exit
Bye

C:\Documents and Settings\Administrator>

五、操作数据库数据的一般步骤

1、启动MySQL服务器
2、登陆数据库服务器
3、使用某个要操作的数据库
4、操作该数据库中的表,可执行增删改查各种操作。
5、退出登陆。

Explain the ACID properties (Atomicity, Consistency, Isolation, Durability).Explain the ACID properties (Atomicity, Consistency, Isolation, Durability).Apr 16, 2025 am 12:20 AM

ACID attributes include atomicity, consistency, isolation and durability, and are the cornerstone of database design. 1. Atomicity ensures that the transaction is either completely successful or completely failed. 2. Consistency ensures that the database remains consistent before and after a transaction. 3. Isolation ensures that transactions do not interfere with each other. 4. Persistence ensures that data is permanently saved after transaction submission.

MySQL: Database Management System vs. Programming LanguageMySQL: Database Management System vs. Programming LanguageApr 16, 2025 am 12:19 AM

MySQL is not only a database management system (DBMS) but also closely related to programming languages. 1) As a DBMS, MySQL is used to store, organize and retrieve data, and optimizing indexes can improve query performance. 2) Combining SQL with programming languages, embedded in Python, using ORM tools such as SQLAlchemy can simplify operations. 3) Performance optimization includes indexing, querying, caching, library and table division and transaction management.

MySQL: Managing Data with SQL CommandsMySQL: Managing Data with SQL CommandsApr 16, 2025 am 12:19 AM

MySQL uses SQL commands to manage data. 1. Basic commands include SELECT, INSERT, UPDATE and DELETE. 2. Advanced usage involves JOIN, subquery and aggregate functions. 3. Common errors include syntax, logic and performance issues. 4. Optimization tips include using indexes, avoiding SELECT* and using LIMIT.

MySQL's Purpose: Storing and Managing Data EffectivelyMySQL's Purpose: Storing and Managing Data EffectivelyApr 16, 2025 am 12:16 AM

MySQL is an efficient relational database management system suitable for storing and managing data. Its advantages include high-performance queries, flexible transaction processing and rich data types. In practical applications, MySQL is often used in e-commerce platforms, social networks and content management systems, but attention should be paid to performance optimization, data security and scalability.

SQL and MySQL: Understanding the RelationshipSQL and MySQL: Understanding the RelationshipApr 16, 2025 am 12:14 AM

The relationship between SQL and MySQL is the relationship between standard languages ​​and specific implementations. 1.SQL is a standard language used to manage and operate relational databases, allowing data addition, deletion, modification and query. 2.MySQL is a specific database management system that uses SQL as its operating language and provides efficient data storage and management.

InnoDB uses redologs and undologs to ensure data consistency and reliability. 1.redologs record data page modification to ensure crash recovery and transaction persistence. 2.undologs records the original data value and supports transaction rollback and MVCC.

What are the key metrics to look for in an EXPLAIN output (type, key, rows, Extra)?What are the key metrics to look for in an EXPLAIN output (type, key, rows, Extra)?Apr 15, 2025 am 12:15 AM

Key metrics for EXPLAIN commands include type, key, rows, and Extra. 1) The type reflects the access type of the query. The higher the value, the higher the efficiency, such as const is better than ALL. 2) The key displays the index used, and NULL indicates no index. 3) rows estimates the number of scanned rows, affecting query performance. 4) Extra provides additional information, such as Usingfilesort prompts that it needs to be optimized.

What is the Using temporary status in EXPLAIN and how to avoid it?What is the Using temporary status in EXPLAIN and how to avoid it?Apr 15, 2025 am 12:14 AM

Usingtemporary indicates that the need to create temporary tables in MySQL queries, which are commonly found in ORDERBY using DISTINCT, GROUPBY, or non-indexed columns. You can avoid the occurrence of indexes and rewrite queries and improve query performance. Specifically, when Usingtemporary appears in EXPLAIN output, it means that MySQL needs to create temporary tables to handle queries. This usually occurs when: 1) deduplication or grouping when using DISTINCT or GROUPBY; 2) sort when ORDERBY contains non-index columns; 3) use complex subquery or join operations. Optimization methods include: 1) ORDERBY and GROUPB
